What does the acronym NPDES stand for?

• A. National Pollution Discharge Elimination System
• B. National Pollutant Discharge Elimination System
• C. National Pollutants Discharge Elimination System
• D. National Pollution Discharge Elimination and Emission System

Answer: (B)

This question checks you know the exact name of the permit program that controls discharges into U.S. waters. The official title uses “Pollutant” in singular form: National Pollutant Discharge Elimination System. That phrasing focuses on discharging pollutants, not pollution in general, and it names a system designed to eliminate those discharges under the Clean Water Act. The other options alter the key terms—using pollution instead of pollutant, using pollutants in plural, or adding “and Emission”—which are not the proper official name.
